Answer:

1.24atm

Explanation:

First, let's determine the number of mole of oxygen gas.

Using  

n

=

m

M

:

n

(

O

)

=

(

32.00

2

×

15.99

)

 

mol

n

(

O

)

=

(

32.00

31.98

)

 

mol

n

(

O

)

=

1.00

 

mol

Then, let's convert the units of the given temperature to  

K

:

T

(

C

)

=

T

(

K

)

273.15

30.00

=

T

(

K

)

273.15

T

(

K

)

=

303.15

30.00

 

C

 

=

303.15

 

K

Now, let's substitute all relevant values into the equation  

P

V

=

n

R

T

:

303.15

P

=

(

)

 

atm

P

=

1.24

 

atm

Therefore, the pressure exerted by the oxygen gas is  

1.24

 

atm

.
